It just plays (and sometimes blogs)
Tomahawk links (http://toma.hk) are just as easy to give as they are to receive.
Giver: just right-click and copy the link to your clipboard for pasting anywhere you see fit. (like this cool song from Work: http://toma.hk/Fwcaaaab or this Indie Station - aggressive in mood, at least 186 bpm, and medium song “hotttnesss”)
Receiver: just click the link and listen.
